To all 'io/1,0m it may concern 1 llc it known that I, FRANK F. Mnnsnnu,

a citii/Jenv of the United' States, residing at Antigo, in the county ofLanglade and State o liisconsin, have invented a new and use,

ul Axle Steeri1ig-l{nuckle,`of which the following is a, speciiication.

'lhis invention relates 'to on improved will.

posed of e minimum number of parts: h With the foregoing and otheroblects 1n' view which willv appear as thedescription proceeds., heinvention resides in the corn#v hination and arringeinent of parts andin the details of construction hereinafter-described and claimed, itbeing( understood tinted, in whcl ,-4

thatchonges in the precise embodiment of the invention herein disclosed,con be made within the scope oi' whst is claimed, without de urting fromthe. spirit of the'invention.

'lhe cylindrical;axle- 23 which is positioned witl'rits axis verticalwhile in use has ,the trunnions 2.21 concentric ,therewithandisfprovidcdor formed with the cylindricalwbore -2'8 extendin rtherein. The cylindrical. horeQS is of asu icient diameter toaccommodate 'anniversari joint therein which universal is of sizesuflicient tot-ransmit power from. a suitable source to the -vehiclewheel.

In order that thepower may be transmitted to the front Wheels a suitable opening; isjournaled in the casing plate 3 'through which extends the shaft 7 whichis connected 'to the universal joint 33 hy means osuitahle bearing .pinsor pivots 84, it be, ing understood in this connection that the hearingpins 34; lie substantially and rotate ina plane which extends throughthe axis of the cylindrical axleQS and trunnions 24, this insuring thatthe spindle may properly turn about the trunnions 24 and the universaljoint will accommodate said turning. The. -spindle 25 is provided withformed therein which extends axle 23 and may be considered tion of thehere 28. Mounted Within the opening in the spindle is the shalt 32connect-ed at its inner end to the universal joint end having its outerend provided with a squared portion d0 which fits Within and isadapte-dto rotate a cap 39 provided with a square aperture all. therein.The said cap engagenient with a wheel 3G of which the hub only has beenillustrated. v ihe projections 37 radiating therefrom represent theflange members to which the spokes of the Wheel are bolted. Thefinnersurface of the wheel as at 38, lines in contact with and is held against27 which thereby holds the Wheel in position upon the said spindle.

' Although no means have been' illustrated for ,preventing thewheel fromsliding oli" of the spindle, it is to be understood in this conneel thatany of the usual means may be en ploy/edit being understood that a Wheelhun has been illustrated only for the purpose of showingtlie manner inwhich the power may be transmitted thereto.

thereto. The shoulder 2.7 holdsthe4 roper position theneon.; Vbore 3lextending surface of the spindle is not a part of my invention und maybe of the usual construction.

The advantage of the construction herein set forth will he readilyAapperent to those skilled in the ort and may ne briefly summed up asfollows :-T'he spindle, nxle and trim 'nions are formed integral, aremilde from .a single forging end are cylindrical 1n our line andtherefore may he readily turned. The bore extending within the axle, (ithe ing understood in this coiniection that the word-axle refers to themember the Vehicle axle 1 when reierred to Will he.

`spoken of as the vehicle axle) is cylindricel in outline and concentricwith the cylindrical Within the spindle.. The casingcontacts with theaxle as well 'with the trunnions and therefore insures en ex tendingbearing surface therewith. The ces-- ing being formed of a rear plateand the tivo removable sections fastened thereto, allows the entireconstruction to be readily teken apart or assembled so that the entiresteering axle knuckle may be retained in un operativo condition. Thecasing being'fornied with the outlying .flanges allows the vehicle axlel to be hanged at its ends which construction al lows the axle to bereinforce-d andV 'to thereby successfully stand the strain et the pointupon which the most strain occurs.

Having thus fully disclosed the mestruation and pointed out theadvantages of my improved construction what I claim to he new andoriginal- With me is:-

l. In a power-transmitting Ide', the'fcomhinatio'n of a housingcomprising a back plate 1und two front members,

stoermg linucsaid housing forming al central journal box with relativelysmaller journalboxes at the ends thereof; an,axle-tru1niionspindlemember iournaled within said housing and ndapted to rotate about theaxis of the axle and thetrunnions, said member being provided with abore extending transversely of seid."

2. In a power transmitting steering knuckle the combination of, ahousingformed with a back plate formed with an outstanding flange, fronthousing .memberO formed with cylindrical bores therein a.. havingflanges outstanding therefrom, adapted to be held to said plate flange,ian naled Within said housing and turn about its longitudinal axis,trunnions formed concentricv with and at said axle, a spindle positionedcent-rally und extending radially from said axle, said spindlc providedwith a longitudinal bore communicatingl with a relatively larger borepro` vided transversely of said axle.
